Abstract
Indole moiety is often found in different classes of pharmaceutically active molecules
having various biological activities including anticancer, anti-viral, anti-psychotic, antihypertensive,
anti-migraine, anti-arthritis and analgesic activities. Due to enormous applications
of indole derivatives in pharmaceutical chemistry, a number of conventional synthetic
methods as well as green methodology have been developed for their synthesis. Green methodology
has many advantages including high yields, short reaction time, and inexpensive
reagents, highly efficient and environmentally benign over conventional methods. Currently,
the researchers in academia as well as in pharmaceutical industries have been developing
various methods for the chemical synthesis of indole based compounds via green approaches
to overcome the drawbacks of conventional methods. This review reflects the last ten years
developments of the various greener methods for the synthesis of indole derivatives by using microwave, ionic liquids,
water, ultrasound, nanocatalyst, green catalyst, multicomponent reaction and solvent-free reactions etc. (please
see the scheme below). Furthermore, the applications of green chemistry towards developments of indole containing
pharmaceuticals and their biological studies have been represented in this review.

Abstract
Ordered mesoporous siliceous material has been identified as one of the key elements of the catalysis concept. Here we report an efficient Friedel-Crafts reaction of indoles with isatins catalyzed by PWA/MCM-41, which got the di(indolyl)indolin-2-ones derivatives with high yield. Moreover, the catalysts were characterized by XRD and SEM/EDS, the EDS spectrum indicated that the catalyst used in this reaction also contains tungsten, and the proposed mechanism for the synthesis of 3,3-di(indolyl)indolin-2-ones was also discussed. Finally, the catalyst can be reused repeatedly for several times without obvious loss of activity.

Abstract
An efficient and green protocol for the synthesis of functionalised spirooxindole derivatives is described. This involves the reaction of in situ-generated keto-enaminones with N-alkylisatins in the presence of isothiocyanates.
